We see Buggy's twin sister in the chapter, in flashback, and in the present
Her name is "Juggy"; she has GIGANTIC DONKAROOS, I MEAN, SOME REAL GALOOMBAS, and her nips are so big/round they're poking through her shirt. Her red nose, however, is cute and dainty.
Juggy: "Can't believe the day would come, when I'd join my pathetic baby brother's Crew.. What dumb sap crawled out of a tree and made Buggy a Yonkou? The Marines are such showy idiots... Well, I guess I have to thank both those defenders of scum and fake justice, and my bombastic brother... if Cross Guild means I get a shot at Honking Dracule Mihawk, ohhhhh yeahhhhhhhh."
Narrator Box: "Queen of Clowns, the 'Cheery Cherry Cream Pie' of the New World, and Captain of the Secret Assassin Guild, Bloody Nose: Rocks D. Juggy."
